To all whom it may concern:

W citizen of the United States, residing at.

Be it known that l, EARLW. Wanner, a

Butte, in the county of Silver Bow and State of Montana, have invented certain new and useful Improvements in Centrifugal EX- tractors, of which the following is a specification.

This invention relates generally to drying machines, and has more particular reference to a machine of the centrifugal type, wherein moisture may be expeditiously discharged from clothes or any form of material in the operation of the machine. 15 7 ceptacle, while the same is disposed within the machine, and then again fill the same.

A further and important object is to provide simple and efficient operating means for locking the ,material receptacle within the machine, and holding the same rigidly therein during the operation thereof.

Yet another object is to provide a particular bearing construction for the rotary material holder, which bearing construction will overcome the great vibration and shaking of the machine, which is a disadvantage now present in practically all forms of centrifugal driers.

A final salient object is to provide a machine of this character that may be mannfactured, installed and operated at minimum cost, and one that is not liable to become out of order, the same comprising relatively few parts, and these correlated in such a manner as to reduce the possibility of disarrangement to a minimum.

view as the nature of the invention will be better understood, the same comprises the.

novelform,combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

cord-ance with the present invention, the drive pulley of the machine being removed in order that the before mentioned bearing construction may be more clearly viewed. 7

Figure 2-is a fragn'ientary elevational view of the machine, the' splash guard belt thereof being shown in an open position, and partly in cross section, whereby when in an open position, the material receptacle may be readily rolled out and upon the floor for allowing anew filled container to be dis posed within and associated with the machine.

Figure 8 is a detailed vertical sectional view of the machine taken at right angles to Figure 2, and

Flgure l1s a-detailed elcvational view of a band locking construct on constituting an essential feature of the present invention,

whereby the material container may be locked within the machine.

Now, having particular reference to the drznvings, 5 indicates the floor of the shop,

within which the present machine is to be installed." This floor 5 is formed at an appropriate point with a circular-shaped well or depression 6 of relatively slight depth,

said depression or well being itself centrally formed with a circular socket 7.

Disposed within this floor well or depres-- sion is the lower end of a skeleton, generally rectangular-shaped metal frame8 that comprises a lower horizontal fiat-like bar 9 that is secured within the well through themedium of heavy bolt connections 10; preferably three vertically extending bars 11 that are integrally joined at their upper ends to a central substantially rectangular shaped plate 12, through the medium of inwardly extending arms or bars 13.

The low'enhorizontal bar 9 of the skeleton open frame 8 is formed upon its bottom side with a circular head ll that engages within the socket, 11 of the floor well or depression 6 for assisting the bolt securing meansinthe maintaining of the frame against vibration. Carried by the top side of this head 14L is a suitable ball bearing 15, that is socketed at its top side for thereception of a pintle 16,

its

pendent from the central point of. a material basket supporting platform 17, that is preferably of circular shape shown by the'dotted lines in Figure 1.

' Extending upwardly from-diametrically opposite points of this platform edge are arms 18 that are connected at their upper lltl ends by'a cross bar 19. Secured at its lower end to said cross bar is a vertical shaft 20 that extends through a collared opening 21 in the substantiallyrectangular shaped plate 13 of the open skeleton frame 8, the upper end of this shaft being equipped with a pul- 'Iey 21, whereby the material basket supporting platformmay be rigidly rotated.

Inter-connecting the arms 18 of the platform 17 at one edge thereof are outwardly extending substantialy semi-circular shaped 1 spaced bands 22, that prevent the displacethe machine.

- gagement.

may be 7 In order to This locking means constitutes the provision of a bail shaped lever25, that is hinged to the free endof the member 24, and

the same is adapted to be engaged through a loop member 26, also hingedly secured to the free end of the complementary member 23. The bail shaped lever 25 is formed "at its unhin ed end with a handle 27, and it will be 0 vious that after the basket has been positioned upon the platform, the members 23 and 24 are to be swung inwardly towards each other, after which the lever 25 engaged through the loop 26, and the same subsequently swung upon its hinge to the positionvshown in Figure 1, for maintaining the members 23 and 24in locked en- Upon the inner-side'of the rigid bands 22 and locking bands 23 and 24 are rubber bumpers 27 that create a wedging action onto the material basket A for an obv1ous purpose. I l

. prevent the basket from creepmg upwardly during the rotation of the platform, the arms'l8 of the platform are formed. adjacent the upper ends with in- 29, through which the drive shaft 20 of the b wardly extending shoulders 28, Figure 3, that will engage the upper end of the basket. Adapted to be disposed .-upon the skeleton rame carrying plate 12 is ashaft bearing machine 1s to be extended. This bearing 2.) is formed at its periphery with spaced pairs of separated ears 30 and pivotally disposed between the ears of each pair as at 31 is the eyed end of a pin 32. I

The four corners of the skeleton frame plate 12 are formed with upstanding ears or lugs 33, each of which is formed with an opening 34, through which loosely-engages described, for preand its wabbling movement the adjacent pin 32. At the eyed ends of these pins, the same are screw threaded for receiving nuts 35, and surrounding these pins between said nuts and said ears or lugs 33 are expansible coiled springs 36, that cooperate with each other in maintaining the bearing 29 centered, and at the same time taking up the'vibration incident to the rapid rotation of the material supporting platform. I

It will be obvious that the position of the nuts 35 upon these pins vwill result in the proper tensioning of the springs 36. Surrounding the machine is a sheet metal substantially Y cylindrical shaped splashguard- 37, that is formed with an outlet opening for the basket, the same adapted to be closed durin the operation of the machine, through t e medium of a door 38.

The material basket A is of course to be a of wire mesh or other foraminous material,

and the same is mounted u on suitable wheels to facilitate the ing of the same with respect to the platform 17. i a

This platform 17 must be on a level to the floor surface 5, "and it will be clearly apparent from the foregoing, that after the moisture has been extracted from the material in one basket, the same may be rolled off of the platform onto the fioor surface and another basket rolled thereon, and subsequently locked in the machine, and the'same subjected to a centrifugal action.

I do not wish to be limited to the specific structural details shown in the drawings and set forth in the specification, insomuch 'as in the future practice of the invention, departures may be-had therefrom, without effecting the spirit and scope of the appended claims.

Having thus described my invention, what I claim'as new, and desire to secure by Let- .ters Patent, is:

1. In a centrifugal drier'of the character described, a vertically positioned rigid frame anchored at one end .to a base, a second frame disposed within said rigid frame for rapid rotation, said'second frame including a material basket supporting platform,

means upon one side of said second frame for limiting the movement of the material basket in one-direction, means at the other side of said second frame for securin the basket upon the platform, and means w erey said;second frame may be rapidly rotated.

. 2. In a described, a vertically positioned rigid frame anchored at one end to a base, a second frame disposed within'said rigid f-game for rapid rotation, said second frame including a material .basket supporting platform, means upon one side of said second frame for. hmitmg the movement of the maremova or position- 5 and a splaslrshield disposed around the rigid provided with a. doorfopening,

frame and whereby the materialbasket may be passed therethrough.

3. In a centrifugal drying machine of the Hi character described a vertically disposed skeleton frame anchored at one end to a base, a second open frame disposed for rigid rotation Within said first mentioned frame and including a material basket supporting platform, a shaft extending vertically from said second frame passing through an open- 1 ing in the upper portion of said rigid frame, a laterally movable and cushioned bearing for said shaft disposed upon the upper member of said rigid frame and means carried by said frame, whereby the second frame may be rapidly rotated.

In testimony whereof I aflix my signature.
